Answer:1/11

Step-by-step explanation:

Let the yellow cubes be x

yellow = x

blue = 2x                // Blue cubes is twice of yellow

Green = 8x              // Green is four times of blue

Ratio:

Yellow : Blue : Green

  1       :   2    :     8

P(Yellow) = 1/11

Nicole used a total of 5 1/6 gallons of gas while driving her car. Each hour she was driving, she used 5/9 gallons of gas what w
Gennadij [26K]

Let's write the total of gallons in improper fraction:

Step 1: Multiply the denominator by the whole number

6 × 5 = 30

Step 2: Add the answer from Step 1 to the numerator

30 + 1 = 31

Step 3: Write answer from Step 2 over the denominator

5 1/6  = 31 / 6

Let's divide the total gallons by what she used each hour to get the number of hours:

\dfrac{31}{6} \ : \ \dfrac{5}{9} = \dfrac{31}{6}\  \cdot \ \dfrac{9}{5} =  \dfrac{31}{2}\  \cdot \ \dfrac{3}{5} = \dfrac{93}{10}

Let convert the improper fraction to mixed number:

93/10 = 9 3/10

<h2>She was driven a total of 9 3/10 hours</h2>

How do you work out 1/10 of £1? 3/10 of £1. 1/5 of 50p. 1/5 of 50. 1/2 of £1.
neonofarm [45]
To find a fraction of an amount you divide by the denominator and times by the numerator (divide by the bottom times by the top)

£1 divided by 10 is 10 pence
10 pence times 1 is 10 pence

£1 divided by 10 is 10 pence
10 pence times 3 is 30 pence

50 pence divided by 5 is 10 pence
10 pence times 1 is 10 pence

£1 divided by 2 is 50 pence
50 pence timed 1 is 50 pence

1/3 = /6<br> - 1/6 = /6<br><br> How do you find the unlike denominator. Can you explain
lakkis [162]

Answer:

Okay So I see you need to change 1/3 to a denominator of 6

You don't do anything to the -1/6

But to change the 1/3 you need to multiply 3 and 1 by two, which is 2/6

And the -1/6 stays the same
